【発明の詳細な説明】 ［産業上の利用分野コ・ 本発明はフロート弁で用いられるフロートに関する。[Detailed description of the invention] [Industrial application fields] The present invention relates to floats used in float valves.
［従来技術］

きるるので好適である。[Prior Art] It is preferable to configure the float valve so that the buoyancy of the float can be adjusted according to the specific gravity of the liquid being handled, since this allows one float valve to operate well with various liquids.
上記のような要請に対して、例えば実公昭５９−１９１
６７号公報においては、中空フロートに塁を設け、該フ
ロートの内部に粒状の重りを入れて浮力を調整する技術
が開示されている。しかし、この技術に係るフロートは
構造が複雑である。そして重りが固定されていないので
、重りが移動してその度に浮力が変ってしまい、フロー
ト弁の作動特性が一定にならないという問題点があった
。For example, in response to the above request,
No. 67 discloses a technique in which a hollow float is provided with a base and a granular weight is placed inside the float to adjust the buoyancy. However, the float according to this technology has a complicated structure. Since the weight is not fixed, the buoyancy changes each time the weight moves, causing the problem that the operating characteristics of the float valve are not constant.
また、実公昭６０−２９６９９号公報において、単泡性
スポンジを圧縮して体積を変化させることによって浮力

しかし、膨潤材質を用いる構造を採用しているた゛め、
調整できる浮力の範囲が狭く且つ浮力調整が難しいとい
う問題を有している。However, because it uses a structure that uses swelling materials,
The problem is that the adjustable range of buoyancy is narrow and buoyancy adjustment is difficult.
［発明の目的］

［発明の構成コ
本発明のフロート弁のフロートは、重りを取付けられる
凹部を設けている。[Structure of the Invention] The float of the float valve of the present invention is provided with a recessed portion to which a weight can be attached.

、そのなめフロート弁の作動特定も一定する。[9 Effects of the Invention] The float of the float valve of the present invention having such a configuration is as follows:
The buoyancy of the float can be adjusted by fitting a weight predetermined according to the specific gravity of the liquid to be handled (for example, gasoline, diesel oil, kerosene, etc.) into the recess in the float. Therefore, the buoyancy can be adjusted easily and accurately, and the structure of the float itself is simple. Also,
Since the weight does not move, the buoyancy does not change, and the operation of the float valve remains constant.
［好ましい実施の態様］
本発明の実施に際して、フロートに組合される弁体を球

能が向上する。[Preferred Embodiment] When carrying out the present invention, it is preferable that the valve body combined with the float is configured in a spherical shape, and the valve is opened and closed by moving the spherical valve body in a direction perpendicular to the valve seat. With this configuration, since the tip of the valve body has a nearly flat shape, the valve opening amount becomes large relative to the stroke of the valve body, and as a result, the responsiveness of the valve improves. Further, since the spherical valve body has an automatic centripetal property with respect to the valve valve when the valve is closed, sealing performance is improved.
［実施例コ
以下添付図面を参照して本発明の一実施例にっいて説明

第１図は、ポンプ装置１の気液分離室２において本発明
のフロート弁のフロート１ｏを設けた場合を示している
。FIG. 1 shows a case where a float 1o of the float valve of the present invention is provided in a gas-liquid separation chamber 2 of a pump device 1.
フロート１０には凹部１２が形成されており、この凹部

て、凹部１２内へ嵌合される。A recess 12 is formed in the float 10, and a spherical weight 14 is removably fitted into the recess 12.
A plurality of weights 14 are provided, and although the dimensions and volume of the plurality of weights are the same, their weights are different, and the i& One weight 14 of suitable weight is selected and fitted into the recess 12.

れた気体の流出路、符号３４は液流出路である。The float 10 is fixed to a rod 16, and the rod 1
6 is fixed to the swinging rod 2o by a pin 18. The swinging rod 20 is rotatably attached to the pivot point 3o, and a valve body 26 is rotatably attached to the swinging rod 20 by a pin 22. The valve body 26 has a spherical shape (in the illustrated embodiment, a hemispherical shape), and as shown in FIG. 1, comes into contact with the valve seat 28 to close the valve. That is, float 1o
, the rod 16, the swinging rod 20, the valve body 26, and the valve seat 28 constitute a float valve. Here, reference numeral 32 indicates a stopper, reference numeral 33 indicates a gas/liquid inlet, 35 indicates an outlet for the separated gas, and reference numeral 34 indicates a liquid outlet.
気液分離室２内に液が溜ると、フロート１０は枢点３０

の結果、弁体２６と弁座２８との当接が解除されてフロ

路３４に流出する。When liquid accumulates in the gas-liquid separation chamber 2, the float 10 moves to the pivot point 30.
It rotates counterclockwise in FIG. 1 about . As a result, the contact between the valve body 26 and the valve seat 28 is released, the float valve becomes open, and the liquid in the gas-liquid separation chamber 2 flows out into the liquid outflow path 34.
このような作動を確実に行うためには、気液分離室２内

嵌合すれば良いので、浮力調整作業が簡単である。また
重り１４が凹部１２内で動いたり外れるおそれがないの
で、フロート弁の開閉作動特性が一定している。In order to perform such an operation reliably, it is necessary to adjust the buoyancy of the float 10 according to the type of liquid flowing into the gas-liquid separation chamber 2. In this case, the buoyancy adjustment work is simple because it is sufficient to fit into the recess 12 a weight 14 having an optimal weight predetermined according to the type of liquid. Further, since there is no risk that the weight 14 will move or come off within the recess 12, the opening and closing operation characteristics of the float valve are constant.
なお、図示の実施例において、弁体２６は球面状に構成
されており、その先端の形状は平面に近くなるので、弁
開閉に際して応答性が非常によい。In the illustrated embodiment, the valve body 26 has a spherical shape, and the tip of the valve body 26 has a nearly flat shape, so that responsiveness is very good when opening and closing the valve.
また、球面状の弁体２６は弁Ｍ２８に対して正確に当接
しようとする求心性を有しているので、弁閉時のシール
性が良い。Further, since the spherical valve body 26 has a centripetal property that tends to accurately abut against the valve M28, the sealing performance when the valve is closed is good.
［まとめコ

Moreover, since the weight does not move and the buoyancy does not change, the operating characteristics of the float valve remain constant.
